Measuring bio-energy crops' carbon footprint

Energy crops are likely to play an increasing role as a low carbon option in the UK's energy mix in the future, say scientists.

A team of researchers from the Centre for Ecology and Hydrology are collecting data of how much carbon is locked in the soil as the crops grow.

They hope to produce a UK-wide map, allowing landowners to assess whether growing the crops on their land will help cut emissions when they are burned to generate electricity.
